I have the following code

<!DOCTYPE HTML>
<html>
    <head>
    </head>
    <body>
        <div class="full-details-box" name="full_details_box" id="full-details-box"></div>
        <hr />
        <script type='text/javascript'>
        function show_3136(){
            document.full_details_box.style.display='block';
        }
        show_3136();
        </script>
    </body>
</html>

I get the error: window.document.full_details_box is undefined

I get the error for the line:

document.full_details_box.style.display='block';

But I do have a <div> element with the name full_details_box, so why the error?
